Post-mortem system analysis
by František Šumšal 21 Nov '18

21 Nov '18

Hello, We're trying to revive CentOS CI for systemd, unfortunately we encountered an issue[0] which prevents the system from booting. That wouldn't so be bad, however, debugging such issues without a serial console is a pain. Not sure if I overlooked something on the CI wiki, but is there any way to connect to the machine via other means to either debug it when it's still alive, or at least get the filesystem contents so it could be properly analyzed? Thanks! [0] https://github.com/systemd/systemd-centos-ci/issues/18#issuecomment-4402058… -- GPG key ID: 0xFB738CE27B634E4B

Hi folks, I've raised a request in the bug tracker[1] for creating an account on ci.centos.org. So that we can start working on migrating end2end tests for `Openshift Do` project there. It is a high priority issue for us now. as of now, It seems like the bug tracker is down. It will be very helpful If some one can respond to the request.

userspace-containerization-ci-slave06 is offline
by Jiri Popelka 12 Nov '18

12 Nov '18

Hello, I've been looking at why all the recent jobs in https://ci.centos.org/job/user-cont-conu-pr/ are pending. The first pending job in the queue says 'userspace-containerization-ci-slave06 is offline', so I checked https://ci.centos.org/computer/userspace-containerization-ci-slave06/ but don't see anything I could do there to resolve it. I can 'ssh userspace-containerization(a)slave06.ci.centos.org' just fine, so it doesn't seem to be offline. What can I do to debug/resolve it ? Thanks, Jiri

Upgrading Jenkins sometime in the next couple of days
by Brian Stinson 29 Oct '18

29 Oct '18

Hi Folks, There are a couple of pending security fixes to Jenkins and plugins outstanding. I'll be restarting the ci.centos.org master as soon as we can find a lull in the queue. Jobs should pick up where they left off, and get queued back when the master returns. I'll send a note here when we're finished up so we can keep track. If you have any questions let us know here or in #centos-devel on freenode. Cheers! -- Brian Stinson CentOS CI Infrastructure Team

I am looking for a way to use python3 on Jenkins slaves. Can someone provide me more details how it can be done ? The simplest way seems like installing rh-python* package and enabling it via scl. -- -- Siteshwar Vashisht

[apps.ci.centos.org] Service degradation 27-Sept-2018 to 28-Sept-2018
by Brian Stinson 28 Sep '18

28 Sep '18

Summary: A large subset of the application nodes in apps.ci.centos.org were placed in an unschedulable state around 13h00 UTC on September 27th. Nodes were rebooted and service was partially restored, but new behavior was exhibited overnight. Pods were able to schedule on the nodes but DNS was not functional. DNS service was restored at around 15h00 UTC on September 28th. Timeline: 27-Sept-2018 13h00 UTC - 28-Sept-2018 15h00 UTC Root Cause: A previously applied update (applied around 17-August) to selinux-policy caused some files to be relabeled. We did not, at the time, schedule a reboot, but routine restarts of the docker service caused the nodes to enter a degraded state. Further file relabels caused the node boot process to complete, but also in a degraded state. Recovery: Completed the rest of the pending updates, and rebooted the nodes to clear the node-schedulable degradation. (27-Sept) Triggered a full autorelabel and rebooted the nodes to clear the node-boot degradation. (28-Sept) Preventative Measures: - Consider rebooting the nodes more often, perhaps on a regular schedule to catch OS upgrade problems - Complete the openshift-monitoring EPIC in the CI backlog, which will add better checks for DNS. Thank you very much for your patience during this outage. -- Brian Stinson CentOS CI Infrastructure Team
